Emergency Protocol: What to Do Exactly When Your Dog Eats Chocolate

By MeowWonder Safety Team Published: 2026-06-02

Discovering a torn chocolate wrapper on the floor is a pet owner's worst nightmare. Chocolate contains theobromine and caffeine — methylxanthines that, per ASPCA Animal Poison Control and AVMA clinical guidelines, dogs metabolize far more slowly than humans .

Why Chocolate Is Toxic to Dogs

Theobromine is the primary toxic compound. Dogs metabolize theobromine with a half-life of ~17.5 hours vs humans at 2-3 hours. Severity depends on chocolate type (baking chocolate has 10× more than milk chocolate), body weight, and amount consumed.

Theobromine content by type:

  • White chocolate: ~0.25 mg/g — low risk
  • Milk chocolate: ~1.5-2 mg/g — moderate risk
  • Dark chocolate (60-70%): ~5-8 mg/g — high risk
  • Baking chocolate/cocoa: ~14-26 mg/g — EXTREME risk

Emergency Protocol

Step 1: Assess (2 min)

Gather: chocolate type (bring wrapper), estimated amount, dog's weight, time of ingestion, symptoms present.

Step 2: Calculate Risk

  • ≤15 mg/kg: Low — monitor at home
  • 15-40 mg/kg: Moderate — call vet now
  • 40-60 mg/kg: High — ER immediately
  • >60 mg/kg: Critical — life-threatening emergency

Step 3: Call Poison Control

ASPCA: (888) 426-4435 · Pet Poison Helpline: (855) 764-7661. Do NOT induce vomiting without professional instruction.

What NOT to Do

  • Don't wait for symptoms (may take 6-12 hours to peak)
  • Don't give salt water
  • Don't give activated charcoal at home (aspiration risk)
